all,

    I too reduced my trim tab from the factory recommended 8" (circa 1989 !)
to 6" . I made my own belcrank from 1/8" aluminum angle shaped just like one
from the RC model store but about .75 inches tall. When flying with one or
two people or either tank full or empty I still have enough authority with
the long throw servo....

Happy Flying !
